1. A method comprising the steps of:
receiving, at an antenna array of a user device, from an access point, a plurality of transmit beams having first widths;
measuring, with said user device, using a receive beam having a second width, said second width being wider than said first width, a quality metric of each of said plurality of transmit beams;
determining, with said user device, angle of arrival for at least a given one of said plurality of transmit beams having a highest quality metric;
said user device advising said access point of results of said quality metric measurement;
receiving, at said antenna array of said user device, from said access point, a selection, based on said advising, of a best one of said plurality of transmit beams for transmission from said access point to said user device; and
forming, at said antenna array of said user device, a receive beam, having a third width, along said angle of arrival for said given one of said plurality of transmit beams having said highest quality metric, said third width being narrower than said second width.
